Chairside provisional implant crown construction: a clinical technique
Dental Update, 2022Provisional restorations provide numerous advantages during dental implant treatment including manipulation of the peri-implant soft tissue contour to optimise the aesthetic outcome. Chairside construction expedites this stage of the treatment to a single visit for the benefit and convenience of both the dental practitioner and patient.

Micro-CT analysis of 3D printed provisional crowns fitting
Technology and Health Care, 2023BACKGROUND: The provisional crowns (PR) play an important role during the course of fixed prosthesis treatment. The fitting of PR varies and depends on various factors. OBJECTIVE: The aim of the study was to evaluate the marginal and internal fit of PR produced by three-dimensional (3D) printing technique and to compare those with PR made by the ...

A safe technique for removal of provisionally cemented crowns
Journal of Endodontics, 1993A technique is presented for removing full-cast crowns and porcelain crowns that have been temporarily or provisionally cemented. A rubber dam retainer clamp with rubber dam attached is placed on the crown and clamped near its margins. Steiglitz forceps are used to apply pressure and leverage. The assembled unit is removed with the Steiglitz and safely

Colour stability of provisional crown and bridge restoration materials
British Dental Journal, 1998In an in vitro study to determine the colour stability of provisional restoration materials, the PMMA synthetics Trimm and Cronsin and the bis-acrylic composites Protemp Garant, Protemp Garant NF, Protemp II and Provipont DC were investigated.The colour changes of the cylindrical untreated samples were measured in comparison with samples after 24 and ...

Crown retention and flexural strength of eight provisional cements
The Journal of Prosthetic Dentistry, 2007Few studies have compared the retention of resin-based and zinc-oxide noneugenol provisional cements. Crown retention testing is difficult and variable; therefore, a simpler method of testing by using flexural strength is indicated.The purpose of this study was to measure the retention of base metal alloy castings to dentin provided by 8 provisional ...

The Journal of Prosthetic Dentistry, 2007
Provisional crowns cemented with provisional luting agents are susceptible to washout, marginal leakage, and secondary caries when placed for a prolonged period.The purpose of this study was to examine the effect of incorporating chlorhexidine diacetate (antibacterial agent) into provisional cements on retention and marginal leakage of provisional ...

Color stability of provisional crown and fixed partial denture resins
The Journal of Prosthetic Dentistry, 2005Provisional resins are used extensively during fixed prosthodontic treatment and exhibit varying degrees of color change/discoloration over time. Data are needed to help predict color stability of provisional resins.The purpose of this in vitro study was to measure the color change of 12 provisional prosthodontic materials after immersion in artificial

Marginal fidelity of crowns fabricated from six proprietary provisional materials
The Journal of Prosthetic Dentistry, 1997The most important requirement for an interim crown is suitable marginal adaptation.This in vitro study compared vertical discrepancies of margins for complete crowns made with six provisional materials (Provipont, Protemp Garant, Unifast LC, Triad VLC, Splintline, and Jet).A direct technique was used to fabricate 60 provisional complete crowns on ...

Flexural strength of provisional crown and fixed partial denture resins
The Journal of Prosthetic Dentistry, 2002Provisional prostheses are subject to flexure under function. Selection of the appropriate material for their fabrication is difficult given the limited evidence-based information on the flexural strength of provisional resins.This study compared the flexural strength of 5 methacrylate-based resins and 8 bis-acryl resins used to fabricate provisional ...
